JOHN F. RULE, OI TOLEDO, OT IIO, ASSIGNOR TO THE OWENS BOTTLE COMPANY, OF

' TOLEDO, OHIO, A CORPORATION OF 'OHIO- crass-roams MACHINE.

Application filed September 29, 1922. Serial No. 591,238.

To all whom it may concern: a Be itknown that L-Jonrr F.- RULE a citizen of the Uni (1 States, residing at Toledo, in the county of Lucas and State of Ohlo, have invented new and useful Improvements in Glass-Forming Machines, of which the discharged following is a specification. a

My invention relates, to machines for forming glass articles and particularly to means for dischargingthe articles from the machine at different positions. It is customary in machines of this character to provide on a rotatin mold carriage, a series of molds. from whic the glass. articles are sue cessively discharged, all at the a me PQSltlOIl.

An object of m' invention is to provide means for selective y dischargin the articles at a; plurality of difl'erent isc arging sta tionsp'or positions. Various advantages are obtained from Such a provision" In 'machines having a large output, the bottles or other articles are sometimes delivered more rapidly than they can be properly handled by the conveyors, setting-up apparatus or other automatic equipment ordinarily pro vided for andling the articles as they are om the formingmachine. The present invention provides means. by which the forming machine distributes and delivers the articles to a plurality of such conveyors or other mechanisms.

It is also sometimes desirable where a plurality of different shapes or sizes of bottles or other. articles are being simultaneously produced fin the same machine, to deliver said articlesto a corresponding number of conveyors. It is also sometimes desirable to selectively convey such articles to di'fi'er;

ent leers. ;-These and other objects, as willa pear hereinafter, are attained by the use oi my invention. I

In the accompanying drawings:

' Figure 1 is a part sectional side elevation of a portion of a bottle blowing machine, to

which the present invention is applied.

Figure 2 is a frontelevation of parts shown in Figure 1.

Figurei3 illustrates diagrammatically the development of cams controlling the selective discharge of the bottles.

Figure 4is a fragmentary sectional view showing a mold bottom and 'its'operating mechanism in the act of discharging a bottle. a The invention is herein shown applied to a machine of the type shown in the co-pending application of Leonard DJSoubier, Se-

rial Number 564,183, filed May 27, 1922, although the invention is not limited to any particular construction or type of machine.

The machine comprises a base 10 on which is supported a. stationary central column'll around which rotates a mold carriage 12.

TheJatter-is driven continuouslyby a motor 13 connected thereto through gearin comprising a pinion 14 running in mes with a ring gear 15 onthe. mold carriage.

Arranged around the carriage area plu rality of'mech'anisms or units each comprising a finishing. mold I6, a'neck mold '17, a blank mold (not shown) and mechanisms for actuating the molds and for blowing the glass therein. .After the parison of glass 18 which has been formed in the blank mold,

is blown 'in the finishing mold, a head 19 carrying the neck mold and finishing mold is rotated about a horizontal pivot 20 to swing the finishing mold withthe blown artlcle therein'fiownward from an-invertedto an upright-position. A mold bottom or support 22 is then broughtu in re Tster with the finishing mold and the fitter. opened, leaying the finished bottle 23 sup ported on "said bottom. The mold bottom is removably mounted in a sleeve 2% carried 29 is permitted to swing inward to the Figf 'ure 4 position, thereby tilting the mold, bottom 22 and discharging the bottle. The up and down movementsof the heads 26 are controlled by a 'plurality'of station; i v ary cams 33 and 34.0n which run rolls 35, 1

mounted on elbows 40, carried by vertical stemsgr, rods 36 supported in the heads 26. Each rod36 com rises'a screw threaded; portion 39 on whic is threaded a pinion 38 operated by a hand wheel 37 and intermediate gearin to adjust the head 26 up and down on t e rod 36. In this 'manner, the mold bottom 22 may be adjusted to molds of, different lengths. Each mold bottom may be placed under the control; of either cam track 233 or 3 t. A bayonet slot and pin con charges of glass in succession at said posh nection 41 between the elbow and stem 36 provides a convenient means for swinging the elbow clear of the cams for shifting the control from one cam to another.

The cam track 33 controls the up and down movements of certain of the heads 26,

thereby controlling the tilting of certain of the mold bottoms, while others are independently controlled by the cam track 34. Thus, the positions at which the bottles are discharged are selectively controlled by these coins. Referring to Figure 3, which illustrates diagrammatically a development of the cams 33 and 3d, successive positions of the rolls 35 during a complete rotation of the mold carriage, are indicated by the broken lines 1 to 8 inclusive. It will be noted that at the position 2, a roll 35 on the lower cam 34 has just moved onto the low portion of its cam, thereby tilting the corresponding mold bottom for discharging a. bottle at this oint. At the position 7, a. roll 35 is 011 tlie low portion of the upper com 33, so that the corresponding mold bottom at'this position has been tilted to discharge its bottle. The low portions of the coins, as shown, are at opposite sides of the machine and control nlternam molds so that slternatehottles are discharged at opposite sides of the machine. It will be understood that the'relative position of the low points on the two cams can be varied to an. extent desired, so that the position 0 discharge for bottles controlled by one cam may best any desired distance in advance of the di.-.:hnrge position for the bottles controlled by the other com. It will also be understood that although in the particular errangement shown on the diagram (Fig. 3), alternate bottles are controlled by each cam, the number of bottles controlled by either cam con be varied. Also, the number of cems can be increased, if desired.

Modifications may be resorted to Within the s irit and scope of my invention.
